I have a C8AE 427 1966 block with C8AE heads. Was told this came out of a Cougar. Trying to get a positive ID. Also it has solid lifters and the block though ready for side oiling was not drilled. Any hints out there.

Thanks

Gerry

If the block is marked 66-427 on the rear bulkhead it could be a 352, 390, 410, 428, or a 427.

If the bore size is 4.23" or bigger then you may have a marine or industrial 427. Those were typically solid lifter center oilers.

man love the pic that car is great looking

to mine, with the exception of the block and head #'s. My block # is c3ae-b and the heads are #c4ae-g. It was exactly the same way- solid lifters, center oiler- marked with 1966-427 on rear of block- side oiler bosses cast into rear of block but not drilled. Nowhere else on the block do I see HP or 427 markings. Were there any markings on the block or heads to denote a marine or industrial use engine? I do have the original engine i.d. tag. Does anyone on this forum have access to the info that would de-code the engine tag? Thanks, Dean

The marking C3AE-B would not appear on the same block with 66-427 marks.

I would believe C5AE-B or C8AE-B. These are for the most part meaningless mold identification casting ID that have nothing to do with application or cubic inches. They simply marked parts of the molds for identification of the molds, not the finished engine. The same marks would appear on any size FE.

Post a picture of the engine tag. Many of us have Ford Master Parts Catalogs which show the tag decode information.

It's probably a marine block. The side oiler bulges are on the side of the block but machined away around one motor mount bolt hole. They are good blocks, nothing wrong with them and you can usually buy them cheaper as they little value to the typical "Sammy Sideoiler" buyer who needs the correct numbers matching side oiler for his fiberglass Cobra kit or H code Mach1.

The heads are C8AE-what? If it's -J they are worth money, typically used on early Cobra Jets and supposedly built for the 68 hydraulic 427. If it's -H those are very common and virtually worthless, and i've got a pile of them to sell if you think they are worth much.

than to say "always" or "never" in the same sentence as FORD, but here gos, any block casted as SO, and not drilled, is MOST likely a marine / industrial block,and will also have solid oil passages... Dean, I'd look real close at that C3 casting, make sure its not C8, which would make more sense. Most of these blocks also have a portion of the side oil casting machined away on the left side, at the motor mount area....

above statement...the marine block was selected, at the time of mfg.,for its inconsistent wall specs, or other casting issues...since it was intended for 8.5 compreesion / 4000RPM / and a lake full of water to keep cool...AND therin lies the problem...the lake had no anti-freeze or rust inhibitor, and the block is coming apart inside...boil / shake n bake / media blast etc., will get it clean ???? And 50 miles into the first drive, your new radiator is plugged !!!!

The tag has the following info:

first line: 427 66 6

second line: 5 M 366 S



I would post a photo, but not sure exactly how to post on the forum yet-- however, I did check the production date [5k21] and you are probably right about the c5ae-b being a distinct possibility. The block # is really difficult to read, even after cleaning and a light wire brushing to remove any slag/rust buildup. It must be a late year 1965 block,[nov.21,1965] which would explain the 1966-427 cast into the back of the block.

The tag identifies it as a 427, 1966 model year, assembled in the 5th week of December 1965.

The engine code is 366 which does not appear in my automotive Master Parts Catalog revision April 1969. For that reason and your description I believe it is a marine or industrial engine. There are a couple Forum members who have a Ford Industrial Master Parts Catalog, hopefully one of them will look it up.

The marine / industrial engines run exactly as well as a side oiler given the same parts used in assembly. The center oil system is in my opinion superior to a side oiler for most purposes.

Thanks for de-coding the engine tag! I take it that the #6 one the top line and the letter S on the bottom line are insignificant? You folks are just a wealth of information! THANKS! Dean

The 6 is the change level, which has no meaning without the engineering data. The engine is a 366S, which again doesn't tell me anything without a Ford Industrial catalog, or maybe a Chris craft Marine catalog.

That's one more item off my list of "to-do things" with this engine. Now if I can just stop that d__ned rear oil seal leak, I'll be done with my "list" for good! Dean
